BALL-TRAP.

SPECIFICATION forming part of Letters Patent No. 232,728, dated September 28, 1880.

Application filed February 14, 1880.

To all whom it may concern 'Be it known that we, JAMEs KERSIETTER and JOHN FAGLEY, of Kribbs Farm, in the county of Clarion and State of Pennsylvania, have invented a new and Improved Glass-Ball Trap, of which the following is a specification.

Figure 1 is a side elevation of the trap. Fig. 2 is a plan of the same. Fig. 3 is a sectional elevation of a portion of the trap, on line 00 m, Fig. 2.

Similar letters of reference indicate corresponding parts.

The object of this invention is to provide a glass-balltrap with an automatically-revolving arm and throwing-spring.

The invention consists of a clock-work arrangement whereby the arm and throwingspring are constantly revolved, as hereinafter described.

In the drawings, A represents the frame of the trap, which frame A consists of the base a, the end strips, 1) I), and top 0, so arranged as to form, essentially, a box with open sides.

Fixed vertically in one end of the frame A is the winding-post B, to which are firmly secured the coiled spring 0 and ratchet D, while the toothed driving-wheel E is loosely mounted on said post 13, and is actuated through the medium of its pawl f, that is held engaged with the ratchet D by the spring 9.

Fixed vertically between the base a and top 0 of the frame A is a post, F, on which are keyed the pinion Gr and toothed wheel H.

Near the front of the frame A is fixed the vertical post I, that carries keyed upon it, between the base and top of the said frame A, the pinion K and escapement-whecl L and on the base a is fixed a verge, L, to regulate the movement of the wheels, which verge may be moved by the handle Z to check the motion of the wheel L when it is desired to place a ball in the loop of the spring N.

The driving-wheel E gears with the pinion G and the wheel H with the pinion K, so that when the mainspring (J uncoils, after having been wound up by the turning of the post B with a suitable key, the post I and its attach ments are made to revolve rapidly.

Fixed on the top of the post I, above the top of the frame A, is the arm M, provided with a cross-head, m. 0n the rear end of this arm M is fixed a coiled spring, N, whose arm a extends along the side of the said arm M and a little beyond it, terminating in a loop, 0. Midway of this arm M, and extending all around it, is a grooved boss or projection, 19,

in the groove of which is fixed a wire trigger,

q; and to operate the device to set it the arm n of the spring N is made to engage in a notch, r, of the boss 19, in contact with the trigger q.

Pivoted on the front part of the frame cover or top 0, and held from contact with the trigger g by a spring, 8, is a lever, 0, whose long arm extends over the front end of the frame 6 A, and has attached to it a string, I.

The mainspring 0 having been wound up and a ball having been placed in the loop of the spring N, as shown at 2, which spring N is held down in the notch r of the boss 0, the post I, arm M, and their attachments revolve; then, on pulling the string P, the lever O is brought in contact with the trigger q, causing said trigger q to force the arm n of the spring N to become disengaged from said notch 7 5 r and fly up in contact with the stop a, that is fixed on the cross-head m, and consequently the ball that has rested in the loop of the spring N is projected violently into the air.

In ordinary glass-ball traps the spring that throws the ball is made to revolve by hand, after the word is given to pull the trigger, and hence the marksman can form a good idea of the direction the ball will take, and the operator of the trap can so time the revolution of the spring as to favor any special marksman. In this device, however, the spring retains the same motion all the time, and no marksman has any chance to form an idea of the direction the ball may take.

We are aware that arms and throwing springs like those herein shown are not new; hence we do not broadly claim them 5 but,

Having thus described our invention, we claim as new and desire to secure by Letters Patent 1.. In a glass-ball trap, the combination, with the arm M, spring N, and post I, of the coiled spring 0, ratchet and wheel D E, pawl and spring a b, pinion and wheel G H, and pinion and wheel K L, constructed and arranged substantially as herein shown and described, whereby the said arm M and spring motion of the wheels and pinions is regulated N are revolved. or may be stopped, as set forth.
